The assailant who plowed a truck into crowds celebrating the July 14 Bastille Day holiday in France, killing 84 and injuring hundreds, apparently planned his attack for months and had accomplices who face terrorism charges, authorities said Thursday.

French investigators originally thought Mohamed Lahouaiej Bouhlel, who was shot and killed by police during the attack, had acted alone during the massacre at the Promenade des Anglais in Nice.
